Engineering is our work, Audio is our passion

If you are estimating stability of feedback system, determining bandwidth or decoupling components for your circuit, RC time constant or cut-off frequency is one of essential parameters. This calculator will help you to evaluate cut-off frequency and time constant of RC circuit.

Enter two out of three values; resistance, capacitance or frequency.

You can also enter two values out of resistance, capacitance or time constant.

Get the rest calculated.

You can use scientific notation to enter data (example: 1.25e-3; 529.46e5)

About

Beranek’s Law

"It has been remarked that if one selects his own components, builds his own enclosure, and is convinced he has made a wise choice of design, then his own loudspeaker sounds better to him than does anyone else's loudspeaker. In this case, the frequency response of the loudspeaker seems to play only a minor part in forming a person's opinion."
L.L. Beranek, Acoustics (McGraw-Hill, New York, 1954), p.208.
